Inline Fabrication, Hornady L-N-L Classic Single Stage Press, Quick Change System Top Plate

I did not install the Quick Change System Top Plate by leveling it to the bottom of the base because there are two different bottoms that came on the Hornady L-N-L Classic press. Therefore, I aligned the top plate by squaring it to the top of the press. I have found that if you eyeball the press from the top you can get it pretty closely squared to the plate. God bless and thanks for watching. Highboy
